However, in typical numerical methods, this incompressibility constraint is only enforced at the discrete level, i.e., the finite difference approximation of the divergence operator is zero, but the interpolated smooth velocity field is usually not *analytically* divergence-free, which leads to errors in the flow. I'll discuss some preliminary work that aims to address this issue.
